Die Belastung der Einkommen mit Steuern und Beiträgen ist in Deutschland im internationalen Vergleich hoch. Ferner nehmen die Steuereinnahmen aufgrund der Steuerprogression im Verhältnis zur Bemessungsgrundlage trendmäßig zu. Um den dadurch zunehmenden ineffizienten Keil zwischen Arbeitgeberkosten und Arbeitnehmerbezügen nicht weiter steigen zu lassen oder sogar zu reduzieren, ist eine Reform des Einkommensteuertarifs erforderlich. In diesem Beitrag werden drei Reformvorschläge unterbreitet, die alle zu einer ähnlichen Gesamtentlastung führen würden, aber unterschiedliche Effizienz- und Verteilungswirkungen haben. Die Entscheidung für einen konkreten Tarifverlauf hängt letztlich von politischen Präferenzen ab.

In a recent IWH online note, the IWH suggested that due to “flight to safety” effects, Germany was able to issue government debt at lower rates than otherwise would have been possible. The total savings was calculated to be around Euro 100 billion or about 3 percent of German GDP. This note provides further evidence on the interest savings to the German budget that extend the calculations in two dimensions. Using this refined methodology, we obtain interest savings to the German budget of just under Euro 90 billion.

The declining importance of money in transactions can explain the well-known fact that US interest rate policy was passive in the pre-Volcker period and active after 1982. We generalise a standard cashless new Keynesian model (Woodford, 2003) by incorporating an explicit transaction role for money. In the pre-Volcker period, we estimate that money did play an important role and determinacy required a passive interest rate policy. However, after 1982, money no longer played an important role in facilitating transactions. Correspondingly, the conventional view prevails and an active policy ensured equilibrium determinacy.

Die Wirtschaft in Ostdeutschland (ohne Berlin) dürfte im Jahr 2015 um 1,5% expandieren. Sie partizipiert dank der engen Integration in den gesamtdeutschen Konjunkturverbund am bundesweiten Aufschwung des privaten Konsums und der Investitionen. Wegen der überwiegenden Orientierung der Exporte auf den Euroraum und die angrenzenden mittel- und osteuropäischen Länder dürfte die ostdeutsche Wirtschaft auch von der dort einsetzenden Erholung profitieren. Allerdings gibt der Handel mit Russland wohl weiter nach.

Nach einem moderaten Start ins Jahr 2015 wird die gesamtwirtschaftliche Produktion in Deutschland wieder etwas mehr Fahrt aufnehmen. Der Produktionszuwachs dürfte im zweiten und im dritten Quartal 2015 mit 0,5% sogar über seiner Potenzialrate liegen. Die Inlandsnachfrage bleibt kräftig, und die Nachfrage aus dem Ausland zieht wieder etwas an. Alles in allem dürfte das reale Bruttoinlandsprodukt im Jahr 2015 um 1,8% steigen (66%-Prognoseintervall: 1,3% bis 2,3%).

With a unique loan portfolio maintained by a top-20 universal bank in Germany, this study tests whether unconventional monetary policy by the European Central Bank (ECB) reduced corporate borrowing costs. We decompose corporate lending rates into refinancing costs, as determined by money markets, and markups that the bank is able to charge its customers in regional markets. This decomposition reveals how banks transmit monetary policy within their organizations. To identify policy effects on loan rate components, we exploit the co-existence of eurozone-wide security purchase programs and regional fiscal policies at the district level. ECB purchase programs reduced refinancing costs significantly, even in an economy not specifically targeted for sovereign debt stress relief, but not loan rates themselves. However, asset purchases mitigated those loan price hikes due to additional credit demand stimulated by regional tax policy and enabled the bank to realize larger economic margins.

External conditions for the euro area economy are still favourable, albeit somewhat less so than at the beginning of the year. Oil prices are by more than a third lower than they were on average in 2014, but about 10 USD higher than in January. Long term interest rates are still very low, but by half a percentage point higher than in January. Worldwide growth in production and trade has disappointed in the first quarter of 2015, and recent leading indicators point to no more than a slightly faster expansion of world production for the rest of the year.

The risks of contagion from the Greek crisis to the partner countries appear limited, because financial exposure to the Greek banking sector has been very much reduced. The EU nowadays has instruments with considerable power to fight losses of confidence, and the other countries that received financial assistance in the euro crisis appear politically much more stable, and their economies (including that of Cyprus in the first quarter of this year) have started growing at quite satisfactory rates.

According to our forecasts, the euro area GDP will grow by 1.6% in 2015 and by 2.1% in 2016, as negative factors slowly become less important. Both private consumption and investment will expand at a good pace, and the unemployment rate will diminish, but still remain above 10% by the end of 2016. The main risk is that the Greek crisis has a more negative effect on confidence than initially expected.

Our inflation forecast for 2015 is 0.2%, with the possibility of a mild deflation not excluded. During the first quarter of 2015 rising oil prices were the main contributors to the ascending inflation expectations, while during the second quarter upward surprises over expected inflation have come from manufactured goods and services. For 2016, we expect that inflation will increase up to 1.2%, still below the 2% ECB’s target.
